Information maintained by the Legislative Reference Bureau
Updating the database of the Illinois Compiled Statutes (ILCS) is an ongoing process. Recent laws may not yet be included in the ILCS database, but they are found on this site as Public Acts soon after they become law. For information concerning the relationship between statutes and Public Acts, refer to the Guide.

Because the statute database is maintained primarily for legislative drafting purposes, statutory changes are sometimes included in the statute database before they take effect. If the source note at the end of a Section of the statutes includes a Public Act that has not yet taken effect, the version of the law that is currently in effect may have already been removed from the database and you should refer to that Public Act to see the changes made to the current law.

    "Intellectual disability" means "intellectual disability" as defined in Section 1-116 of the Mental Health and Developmental Disabilities Code.
    "Physical disability" means a disability as defined by the Americans with Disabilities Act of 1990 that meets the following criteria:
        (1) It is attributable to a physical impairment.
        (2) It results in a substantial functional limitation
in any of the following areas of major life activity: (i) self-care, (ii) receptive and expressive language, (iii) learning, (iv) mobility, (v) self-direction, (vi) capacity for independent living, and (vii) economic sufficiency.
        (3) It reflects the person's need for a combination
and sequence of special, interdisciplinary, or general care, treatment, or other services that are of lifelong or of extended duration and must be individually planned and coordinated.
    (b) In this Act:
    "Chronological age-appropriate services" means services, activities, and strategies for persons with disabilities that are representative of the lifestyle activities of nondisabled peers of similar age in the community.
    "Comprehensive evaluation" means procedures used by qualified professionals selectively with an individual to determine whether a person has a disability and the nature and extent of the services that the person with a disability needs.
    "Department" means the Department on Aging, the Department of Human Services, the Department of Public Health, the Department of Public Aid (now Department Healthcare and Family Services), the University of Illinois Division of Specialized Care for Children, the Department of Children and Family Services, and the Illinois State Board of Education, where appropriate, as designated in the implementation plan developed under Section 20.

Independent service coordination includes, at a minimum: (i) outreach to identify eligible individuals; (ii) assessment and periodic reassessment to determine each individual's strengths, functional limitations, and need for specific services; (iii) participation in the development of a comprehensive individual service or treatment plan; (iv) referral to and linkage with needed services and supports; (v) monitoring to ensure the delivery of appropriate services and to determine individual progress in meeting goals and objectives; and (vi) advocacy to assist the person in obtaining all services for which he or she is eligible or entitled.

    "Least restrictive environment" means an environment that represents the least departure from the normal patterns of living and that effectively meets the needs of the person receiving the service.
